Index entries for sequences that are permutations of the natural numbers

FORMULA

a(0)=0, a(1)=1, and thereafter, if A079559(n)=0, a(n) = 2*a(A234017(n)), else a(n) = 1+(2*a(A213714(n)-1)).

a(n) = A054429(A233275(n)). [Follows from the definitions of these sequences]

PROG

(Scheme, with memoizing definec-macro from Antti Karttunen's IntSeq-library)

(definec (A233277 n) (cond ((< n 2) n) ((zero? (A079559 n)) (* 2 (A233277 (A234017 n)))) (else (+ 1 (* 2 (A233277 (- (A213714 n) 1)))))))
